In conclusion, strong or weak EA should be administered for at least 2 weeks to exert a clinically important effect on KOA. Strong EA was better than weak or sham EA in reducing VAS and improving CPM function and was the most effective in alleviating pain intensity and the development of chronic pain of KOA patients. This study will not only increase our knowledge on the effects of strong or weak EA on treating chronic pain in patients with KOA, but also may help acupuncturist to choose the optimal intensity of EA and promote the clinical effect of EA analgesia. The selection of strong EA may be considered for inclusion in clinical guidelines for EA in the treatment of chronic pain of KOA. Moreover, the strong EA should be effective for other chronic pain diseases other than KOA, which will be very helpful in solving opioid overdose.
